Abstract
In a communications network, a cluster switch is provided, where the cluster switch has plural individual switches. An abstraction layer is provided in the cluster switch, such that an interface having a set of ports is provided to upper layer logic in the cluster switch. The set of ports includes a collection of ports of the individual switches. Control traffic and data traffic are communicated over virtual tunnels between individual switches of the cluster switch, where each virtual tunnel has an active channel and at least one standby channel.
